Results: Does Exposure to sunlight affect the amount of Vitamin C in juice? OUR HYPOTHESIS:Experiment TwoHow we tested ourhypothesis...-Two experiment A. How the sun affects vitamin C from the sourceB. How sun affects vitamin C in juice formChemistry 102-02by: Edelweiss Vaovasaand Diana BetancourtEXPERIMENT ONE:Results:About Vitamin C:-Also known as: Ascorbic Acid, L-ascorbic acid, and L-ascorbate-Many health benefits-Chemical formula: C6H8O6-Comes from many citric fruits and vegetablesAbout the Sun:-One of many sources of Vitamin D-The skin synthesize vitamin D from exposure to sunlight and other artificial sources of Ultraviolet B (UVB) light.Sunlight does affect the amount of Vitamin C in juices, increasing the amount in Juice.pineapple orangetreeHamlin Orange treeValencia orange TreeTested before ripening, at ripening, and before ripeningSunlight affect on Vitamin C from the sourceSun System PAR Meter An integrated sensor to measure photosynthetic active radiationwhere we testedVitamin C Strips:Used gives us the range of Vitamin C.Step 1:Step 2:Step 3:Titration ExperimentUsing iodine and starch solution in order to find the amount of Vitamin CValencia Oranges had the most Vitamin C- had the most sun during June- grew during Winter even without the least amount of sunHow sun affects vitamin C in juice form3 cups of each (9 cups total):-one set outside in the sun-one set inside, regular amount of sun*- one set outside, covered- one set inside, covered* our control grouplowersthighest-closed cups on the inside and outside lost Vitamin C, but cups on the outside lost the most. -open cups outside lost a significantly larger amount of Vitamin C than the ones open inside.ConclusionSunlight increases Vitamin C during growth of citrus fruit or vegetables, but diminishes Vitamin C over time in juice form.
